A special addition to the auction is the dinner bell from Kidney Pond Camps, a historic Maine sporting camp that is now one of Baxter State Park’s most popular campgrounds.

“These signs are one-of-a-kind keepsakes for anyone who enjoys hiking and camping in Baxter State Park” said Aaron Megquier, the executive director of the Friends group, in a news release. Many of the signs are well-worn, showing their exposure to harsh alpine conditions — or in some cases, the park’s resident wildlife.

The organization will donate half of the auction proceeds directly to Baxter State Park. The remaining proceeds will support Friends programs such as the Baxter Youth Conservation Corps, a new program that hires teens from the Katahdin region for summer trail work in the park.

Bidding closes at midnight Wednesday, Dec. 6. The auction is entirely online and may be accessed at 32auctions.com/fbsp.
